LONDON -- Former Wimbledon champion Pat Cash is convinced that British No. 1 Tim Henman will not win the Wimbledon title this year.

"If Tim Henman wins Wimbledon I am going to do this show in one of (BBC television presenter and former British player) Sue Barker's old dresses," said Australian Cash on BBC's Today at Wimbledon TV program.

"I am serious, I'll do the show if I'm invited," said Cash after Henman struggled to defeat Swiss Michel Kratochvil in five sets in their fourth round match.

"He (Henman) was pretty average today. He just cannot loosen up, he plays so much better the rest of the year."

Cash, the 1987 Wimbledon champion, believes Greg Rusedski has a better chance than Henman of delivering a home win.

"I think Greg's got a chance. I just don't think Tim does any more. It's all looking good for Greg," said the Australian.

"If he gets through this match (Rusedski resumes at two sets all with Belgian Xavier Malisse later on Tuesday), he's got (Richard) Krajicek and (Mark) Philippoussis. They won't have a day off and they are both injury prone.

"If Tim and Greg get through to the final, then I think Greg will win.

"If Lleyton (Hewitt) gets through I think Greg's got an outside chance because he's got the big game and he can get all over the net.

"I'm just not convinced by Tim. Apart from that, I like the idea of cross dressing," joked the Australian.
